Too bad, I'd be happy to share too, as I'm traveling solo, but I arrive the evening of the 20th. I'll probably book a shared transfer with Clives to save 1/2 the cost. If you're set on using Rocky, maybe ask him if he has any other guests for around that time willing to share. I was booked with Kingsley James last time and my friend cancelled. Wrote him about it and he ended up with another party arriving 1/2 hour later that I could ride with. He only charged me $18.

Good luck!
